1 Claim. (Cl. 100-232) This invention relates to presses and moreparticularly to an improved press operable to compress scrap metal orthe like into compact bales.

it is an object of the present invention to provide an improved balingpress which includes a gathering chain her and a ram therefor which isoperable to move material deposited in the gathering chamber into themain compression chamber of the press.

A still further object of the present invention is the provision of animproved baling press having a pivoted lid operable to verticallycompress the material deposited in the compression chamber.

A still further object of the present invention is the provision of abaling press having improved means for compressing material vertically,longitudinally and transversely.

Still another object of the present invention is the provision of abaling press having an improved means for discharging the compressedbale from the press.

Still another object of the present invention is the provision of abaling press which is sturdy in construction, simple in operation andeconomical to maintain.

These and other objects of the present invention will become moreapparent during the course of the following detailed description andappended claim.

The invention may best be understood with reference to the accompanyingdrawings wherein an illustrative embodiment is shown.

In the drawings:

Figure 1 is an isometric view of a baling press embodying the principlesof the present invention and showing the same in its initial openposition;

Figure 2 is a side elevational view partly in section showing the balingpress with the gathering ram fully extended;

Figure 3 is a view similar to Figure 2 showing the lid fully extended;

Figure 4 is a view similar toFigure 3 showing the longitudinal ram fullyextended;

Figure 5 is a top plan view partly broken away showing the transverseram initially extended with the discharge door closed;

Figure 6 is a view similar to Figure 5 showing the door open; and

Figure 7 is a view similar to Figure 5 showing the manner in which thecompressed bale is discharged.

Referring now more particularly to the drawings, the baling press of thepresent invention comprises a frame 10 which constitutes a meansdefining a compression chamber 12 and a horizontally extending gatheringchamber 14, both of which are rectangular in plan. The frame 10 includesa bottom wall 16 having a pair of parallel side walls 18 and 20extending upwardly therefrom and an end wall 22 extending upwardlytherefrom between one end of the side walls. This end wall 22 has aheight substantially less than the height of the side walls 13 and 20and is preferably built up to have a substantial thickness. Extendingbetween the opposite ends of the side walls 18 and 20 in parallelrelation with the bottom Wall 16 is a horizontal wall 24 which isdisposed at substantially the same level as the upper edge of the endwall 22.

A lid 26 is pivoted between the side walls 13 and 28 just above the endwall 22 by means of a shaft 28 suitably journalled in the side walls.This lid includes a pair of spaced central strengthening ribs 30 towhich a piston rod 32 of a ram 34 is attached. Ram 34 includes the usualcylinder 36 which is pivotally mounted be tween a pair of horizontallyspaced plates 36 suitably mounted on the rear end of the end wall 22. Byvirtue of the pivotal connection of the cylinder with the frame and thepiston rod with the lid 26, ram 34 acts to pivot the lid between an openposition wherein the open top of compression chamber 12 is exposed andan extended or closed position wherein the lid is disposed within theupper portion of the compression chamber in substantially the same planeas the horizontal wall 24.

Mounted above the horizontal wall is a gathering ram unit, generallyindicated at 40, which includes an angular plate d2, the vertical flangeof which constitutes a material contacting panel which forms a verticalend wall or the gathering chamber when in retracted position. Theforward end of a piston 44 of the ram 40' is secured to the rear surfaceof the vertical panel 42 and an associated cylinder as is rigidlymounted above the horizontal wall 24, as by straps d8. Ram 40 isoperable to move the panel through the gathering chamber so as todischarge the material therein into the main compression chamber 12.

Mounted below the horizontal wall 24 is a longitudinal ram unit,generally indicated at 5%, which includes an angular plate 52 having avertical panel shaped to extend within the lower portion of thecompression chamber below the horizontal wall 24 so as to form avertical end wall of the lower portion of the compression chamber 122when retracted. A piston rod 54 is fixedly secured to the panel 52 andan associated cylinder 56 is rigidly secured to the bottom wall of theframe by any suitable means. Ram unit 56 is operable to reciprocatepanel 52 within the lower portion of the compression chamber 12 in alongitudinal direction.

Extending from the side wall 1'8 is a super structure 5'3 upon which ismounted a transverse ram unit, generally indicated at 60. This ram unitincludes a panel 62 disposed within an opening 64 formed in the lowerportion of the side wall 13 adjacent the end wall 22 so as to form alower side Wall of the lower end portion of the compression chamber 12when in retracted position. A piston rod 66 is connected with the panel62 and an associated cylinder 68 is rigidly secured to the superstructure 53 in any suitable manner.

The opposite side wall 20 is likewise provided with a super structure7t! within which a ram unit 72 is mounted. This ram unit 7'2 includes adoor or panel 74 which is disposed adjacent an opening 76 formed in theside wall 26 in a position corresponding to the opening 64 of side wall18. The door or panel 74 is longitudinally reciprocsted into and out ofclosed position with respect to the opening 76 by means of a piston rod78 secured thereto and slidably mounted within an associated cylinder80.

If desired, the entire frame ill may be supported on a 7 chamber and theram unit 44 actuated to discharge the material therefrom into thecompression chamber. After both of the chambers have received a suitablecharge of scrap metal or the like, ram unit 40 is actuated (by means ofsuitable hydraulic controls not shown) so as to the panel 2-2 throughthe gathering chamber into i extended position as shown in Figure 2. Inthis condition, all of the material will be disposed within thecompression chamber 12 and the panel 42, together with panel 52 of thelongitudinal ram unit 55 constitute opposite end wall of the compressionchamber.

As shown in Figure 3, lid 26 is then moved from its open position intoits closed position by actuating ram unit 34. This movement of the lid26 will effect a vertical compression of the material deposited withinpression chamber. Thus, as the lid moves throu h the upper portion ofthe compression chamber, tl material therein will be compressed into thelower portion thereof.

Next, ram unit is actuated to move panel 52 longitudinally through thelower portion of the compression chamber, which movement effects acompression of the material therein into the lower end portion of thechamber 12. As shown in Figure 4, the ram unit 59 in its fully extendedposition moves the panel 52 a distance the outer limit of which isspaced from the end wall 22 of the frame. Stated differently, when theram unit 50 is in its fully extended position, the panel 52 is disposedaway from the end wall 22 a distance substantially equal to the width ofthe openings 64 and 76 formed in the side walls.

As shown in Figure 5, ram unit 6% is next actuated to move the panel 62within the opening 64 transversely through the lower end portion of thecompression chamber toward the opening 76. The initial movement of theram unit 6?; compresses the material disposed in the door 74 is closedby actuation of ram unit 72, panel as is retracted within opening 64 byactuation of ram unit 6%, panel 52 is retracted to the inner edge of thehorizontal plate 24 by actuation of the ram unit 5%, panel 42 isretracted to the outer end of the gathering chamber by actuation of ramunit 4%, and lid 26 is pivoted into its open position by actuation ofram unit .34. This con dition of the press is illustrated in Figure 1.

It is to be understood, however, that the form of the invention herewithshown and described is to be taken as the preferred embodiment of thesame and that various changes may be made without departing from thespirit of the invention or the scope of the appended claim.
